摘要

This paper reports the fossil woods found for the first time in the Jurassic volcanic-sedimentary strata in the central-southern part of the Greater Hinggan Mountains. The fossils occur in the intermediate-acidic pyroclastic sedimentary rocks of the Manketouebo Formation in Horqin Right Wing Middle Banner of Inner Mongolia. According to detailed identification, there are 5 genera with 3 known and 2 unknown species. The main features of these fossils are described and their ages are discussed.   A comprehensive analysis of the combinational features indicates that the fossil woods are middle stage of Late Jurassic in age. The newly found fossil woods provide new paleontological evidence for regional stratigraphic correlation of Upper Jurassic strata in the Greater Hinggan Mountains region.
